Summary
Built in 1952, this dam stands at a height of 19 feet and spans a length of 690 feet, with a storage capacity of 119 acre-feet. Despite being unlisted for its foundations, the dam is classified as a buttress type with a spillway that is uncontrolled, presenting a low hazard potential and moderate risk assessment.
The dam, managed by the Savannah District of the US Army Corps of Engineers, has not been state-regulated but undergoes regular inspections every five years. The last inspection was conducted in 2010, with a condition assessment yet to be rated. With a drainage area of 484 square miles and a normal storage capacity of 94 acre-feet, Cotton Patch Pond Dam plays a crucial role in supporting local irrigation needs and maintaining environmental water resources in Tattnall County, Georgia.
Enthusiasts of water resources and climate can appreciate the significance of Cotton Patch Pond Dam in sustaining agricultural activities and water supply in the region. The dam's presence underscores the importance of proper infrastructure maintenance and periodic inspections to ensure public safety and the preservation of the surrounding ecosystem. As efforts continue to manage the risk associated with the dam's operation, its role in water resource management remains vital for the community and the environment it serves.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
